如果设置了较长的文本,则Textview宽度不会更改

问题描述 投票:1回答:2

我正在开发布局,以显示信用卡和卡片类型图像的最后4位数。如果没有选择任何卡,它将显示一些长于4位卡号的其他文本。选择卡后,它会在TextView中正确显示,但是当设置较长的文本时,它显示不正确。对于较长的文本,TextView不会扩展其宽度。

在更新文本后,您是否尝试在TextView上调用这两个函数?

textView.invalidate();
textView.requestLayout();

说明:https://stackoverflow.com/a/42430695/1062074

更新

以下工作,父布局上的requestLayout将起作用。

parentLayout.requestLayout();
